Pro Micro ATmega32U4 5V 16MHz ATmega328 for ArduinoPro Mini with 2 Row Pin Header for Leonardo UNOR3

Description 1 The Pro Micro is similar to the Pro Mini except with an ATmega32U4 on board 2 The USB transceiver inside the 32U4 allows us to add USB connectivity on board and do away with bulky external USB interface 3 This tiny little board does all work for Arduinotricks that you re familiar with 4 channels of 10 bit ADC 5 PWM pins 12 DIOs as well as hardware serial connections Rx and Tx Running at 16MHz and 5V this board will remind you a lot of your other favorite for Arduinocompatible boards but this little guy can go just about anywhere There is a voltage regulator on board so it can accept voltage up to 6V Blue board If you re supplying unregulated power to the board be sure to connect to the RAW pin on not VCC 4 This latest revision corrects the silk error from the last version of the board so that pin 14 is correctly labeled We ve also added a PTC fuse and diode protection to the power circiut and corrected the RX and TX LED circuit Features 1 ATMega 32U4 running at 5V 16MHz2 Supported under for ArduinoIDE v1 0 13 On Board MINI USB connector for programming4 4x10 bit ADC pins5 12 x Digital I Os 5 are PWM capable 5 Rx and Tx Hardware Serial Connections6 Our Smallest for ArduinoCompatible Board Yet Package Include 1x Module Board
